Early Processing in Sketch Understanding

The Problem: Freehand sketching is both a natural and crucial part of design, yet is almost totally unsupported by current design automation software. We are combining the flexibility and ease of use of paper and pencil with the processing power of a computer to produce a design environment that feels as natural as paper, yet is far smarter. One of the most basic steps in accomplishing this goal is converting the original pen strokes into the intended geometric objects, the early processing part of the task.
